Additional ecosystem context: [Apache Doris](https://doris.apache.org/docs/3.x/sql-manual/sql-functions/scalar-functions/bitmap-functions/bitmap-contains/) and [StarRocks](https://docs.starrocks.io/docs/sql-reference/sql-functions/bitmap-functions/bitmap_contains/) expose `bitmap_contains`, while [ClickHouse](https://clickhouse.com/docs/reference/functions/regular-functions/bitmap-functions) exposes `bitmapContains`. This comparison supports the API naming and the value of a native membership predicate only; it does not imply binary-format or semantic compatibility. Those engines use native bitmap representations, while this PR keeps Spark's existing flat `BINARY` bitmap representation and bucket-local position mapping. -- This is an automated message from the Apache Git Service.
